Sell Wellington apartment privately

Hi Team, I have a Wellington CBD studio apartment which is still under construction with settlement likely to be in October 2024. Due to a change in personal circumstances I’m looking at the option of selling it. I’m well aware that the market has dropped and I’m prepared to take a loss. To minimise my losses, I’m considering selling it privately as just can’t justify paying RE agent $20,000 in fees (commission, marketing and admin etc) as that will basically be my whole deposit gone (once total losses are accounted for). I’m looking for some valuable advice on which platforms are the most cost effective / beneficial to list on. I see Trademe has the platinum package for $1269 which seems to be the go to for most people. I realise that agents will generally have lists of potential buyers and negotiating skills etc however I’ve seen the same properties on Trademe for a while now so clearly the agents are struggling to move them. Personally, I wouldn’t be deterred from purchasing private as long as lawyers are involved at the business end as per the standard process. And to any agents that read this, I appreciate it’s not easy out there at the moment and I’m not trying to diminish your occupation as generally I would utilise your services. Look forward to your comments.
